Getting default PGraphics as variable?
Oct 30th, 2009, 11:31am  
So I know I can make an offscreen buffer ala
buf = createGraphics(width,height,P3D);
buf.beginDraw();

etc-- but if I'd like a function that will either draw to an offscreen buffer OR the main buffer (understanding that the offscreen needs the explicit beginDraw/endDraw), is there a variable or function to access the "default" PGraphics?

Assuming that you have I understand you correctly then the following might help. (I have not tested the code but I don't think it is far off a solution)

Code:

PGraphics3D p3dg;

void setup(300,300,P3D){
   p3dg = (PGraphics3D) g; // Get the graphics object
   buf = createGraphics(width,height,P3D);

  draw(p3dg); // draw to main buffer
  draw(buf); // draw to off screen buffer
}

void draw(PGraphics3D g3){
   g3,beginDraw();
   // ... draw with g3
   g3.endDraw();
}
